Video Recording

Video recording on the G7 is actually a very interesting topic because you have the two cameras to choose from. In terms of recording modes the phone is limited to 4K30 as its highest quality mode, while 60fps recording is enabled only for 1080p. There are also 18.9:9 aspect ratio resolutions at 2268x1080 and 1512x720 at 30fps which give you a wider field of view. EIS is only applied at 1080p30 and below.

In terms of encoding settings, the G7 only uses AVC/H.264 and doesn’t take advantage of the SoC’s more powerful HEVC encode mode. The encoding bitrates are standard for the respective resolutions and capture rates.

Main Camera:     
Wide Angle:        

Recording Mode AVC / H.264
3840p 30fps High@L5.1 - 47.9 Mbps
1080p 60fps High@L4.2 - 24 Mbps
1080p 30fps High@L4 - 17 Mbps

The 60fps capture modes suffer a lot from either a too low encoding bit-rate or the ISP isn’t doing as much processing, as it’s immediately visible that there’s far less dynamic range and detail compared to the 30fps modes. And it happens on both cameras.

1080p and 4K look good on both camera modules, although the lack of OIS is very visible in the wide-angle shooter. EIS functions extremely well and manages to retain a lot of detail – it’s to be noted that the occasional blurring jitter in the videos here is more of an effect of the YouTube transcoding, as the effect isn’t nearly as bad in the original video files.

What I really loved though about the G7 is the wide-angle recording in combination with EIS. I usually don’t enjoy EIS video capture because it really narrows your field-of-view too much in most cases, however on the G7 the wide-angle lens cancels out any disadvantages of the EIS, and you end up with a FOV that’s still wider than most other smartphones, with the benefit of great stabilisation.

The sound recording quality of the G7 was good, although I found that wind noise was a lot more pronounced than in other smartphones.

Overall the only larger criticism here is the loss of picture quality in the 60fps modes as well as overall the lack of being able to capture in HEVC as that would have noticeably increased picture quality without increasing file size.

Speaker Evaluation

LG made some big claims for the speaker of the G7 as it promised some really notable gains with its new design.

During our pre-brief we were presented with a few basic specs: the speaker is 39% bigger than on the G6, and also the resonance chamber is said to be the biggest of any smartphone. Instead of using the speaker housing as resonance chamber, the G7 uses the whole internal volume of the phone. This was also very much achieved thanks to the sealed nature of the phone through its IP68 rating. What this promises is vastly increased bass levels than any other phone.

First up though, let’s measure the speaker loudness. We’re using a flat response calibrated microphone and we’re measuring pink noise at a 40cm distance from the phone. The phone is held both one-handed in portrait mode, as well as two-handed with cupped palms in landscape; both of these should represent common use-cases for most people.

Speaker Loudness

The results are extremely good for the G7, as it manages the loudest results among recent flagships. What is more remarkable still for the G7 is actually the directionality of the sound. Even though it only has one speaker and it’s bottom/side firing, this doesn’t seem to really hinder it much in terms of having excellent frontal directionality. I was really surprised at just how well this works and it easily outperforms even some true front-facing speakers of other phones. The sound directionality and evenness in portrait mode is particularly excellent.

Holding the phone in landscape is tougher though as it’s very much biased towards the side of the speaker and here the phone doesn’t fare as well as other stereo implementations.

Moving on to the frequency response of the speaker, we’re measuring a sweep from 20 to 20KHz, in the same conditions as our previous test, while holding the phone in landscape mode with two hands. All the phones are calibrated to the same loudness, aiming for 75dbA.

Although LG promised a lot of bass through the new speaker, it it actually ends up as one of the worst performers. The phone is significantly lacking in terms of depth, sounding very hollow. This is represented by the low SPL below 400Hz.

Investigating it more, one of the things LG did during the presentations of the phone is to showcase how the sound profile significantly changes when you lay it down on a surface. Indeed, while you hold the phone you can really feel the reverberations on the back glass of the phone. The problem here is that this is just wasted energy that doesn’t translate into any meaningful sound. Putting the phone on a standing surface allows the phone to transfer the vibrations and use the surface to amplify the sound.

I tested this out on my work desk, with once the phone held in my hand on the desk, and then again with the phone’s back flat against the desk.

Looking at the frequency response, we now see all that low frequency energy transfer to the desk and really amplify the low to mid frequencies of the phone, resulting in a much flatter frequency response.

To better represent the difference, here are two audio recordings of the two scenarios. Unfortunately I don’t have a proper omnidirectional recording microphone to capture this too well, so the recording was made with the measurement microphone – the issue with this one is that it lacks sufficient dynamic range and that’s why it sounds more muted. Here’s a recording of flat response speakers that should serve as an apples-to-apples baseline for comparison.

You can switch playback between the two recordings by pressing anywhere on the waveforms, and the recordings are synchronized in terms of their timestamps. This really represents the large audio profile difference between holding the G7 and putting it on a surface.

While this is all good in terms of looking at the frequency response, there’s a big catch when comparing the G7 to competitors. Putting the Galaxy S9+ onto the desk right next to the G7 and repeating the measurement, we actually see the Samsung phone perform even better in terms of bass as well as showcasing a significant advantage in the high frequencies.

When listening to the recording of the S9+ next to the G7, it puts the G7 into context, suddenly makes one question what the actual benefits of LG’s speaker design is. The coup de grâce for LG’s speaker is the fact that other phones don’t need to be put onto on a surface to be able so sound good; the S9+’s sound profile barely changes between holding it or putting it down. The G7 in the other hand just sounds bad when you’re holding it.

The most interesting fact is that when holding the phone, you can squeeze in the back side quite hard – what this does is reduce the internal reverberation and vibrations, and vastly increases the amplitude of lower frequencies actually coming out of the phone, noticeably improving the bass and depth of the audio.

Here’s the thing; while LG’s idea has some kind of merit and does work in some cases, a smartphone is still a handheld device, which by definition you hold it in your hand. Taking all of this into account, I don’t really see LG’s new speaker design paying off and I would even go as far to say that I somewhat prefer the G6’s sound, although that one isn’t great either.

    Another LG flagship device with a way too blue display. I believe I called that when it was announced. Next up, poor update policy (quarterly security updates or worse) and a usual $200-$350 price drop in 3 months.

    Seriously??? You're gonna complain about a problem that almost any smartphone has, and is yet correctable??? What a cry baby! Just like the Galaxy S9 came with a red tint, it was corrected through the rgb display settings. So too can you correct it on the LG G7! As for updates, I've gotten two updates since I got the phone! Yes, I got the G7 and it's an awesome phone! My question for most people hating on it is... Have you even spent time with it??? Then until you do, don't judge!!! I for one, am loving it!!! Specially since I got the BOGO deal at T-Mobile! Making my G7 better than most phones at about $425 each with tax!!! This whole talk about a price drop is what would be expected from someone who probably copies and pastes everyone else's opinions but their own. Smh!

    Seems like your compensating for something in that post

    Not really, no. Just addressing ignorance... Just like I'm addressing your rude condescending.

    That is an... excessive amount of punctuation. As leexgx says here, it seems that you're compensating for something. A bit of insecurity regarding the quality of a product you just spent $850 on, perhaps? Sure, for $425 it's a great deal (any SD845 phone at that price would be), but the review clearly shows that the blue tint cannot be corrected at all. A white point of 7800K is ridiculously high, and a DeltaE of more than 6 at its best is atrocious for a flagship phone in 2018. You might not care about accurate colors, and that's fine, but not even giving users the option is really, really bad. It speaks of either rushed development or just plain bad software development on LG's part. These lapses do not belong in flagship phones in 2018 - the market has moved beyond that quite a few years ago. If LG can't match the basic features of their competitors, they should either quit trying or start making an effort. It's a real shame too, 'cause that display seems great in most other regards (contrast is fantastic for an RGBW panel, brightness is astounding). The camera seems like it could be improved significantly too, given how much better the V30 with the same hardware is. I suppose it doesn't matter much if the pictures are only ever viewed on phone screens and never zoomed, but that's not for me. I'm too much into photography to settle for overprocessed, smudgy pictures.

    Maybe the reviewed screen was bad and the rest are not. It can vary wildly.
  • Valantar - Saturday, August 11, 2018 - link

    As the review points out, at this price point you really shouldn't have to play the LCD lottery. There's this thing called 'quality control', after all.

    No, most better smartphones don’t have this problem. Just look at th displays on the Samsung and Apple phones. Both are far better.

    I have a G6 and I'm stuck at Nougat, Sec Patch March 2017. LG is as well as Samsung one of the worst manufacturers you could possibly buy.
